This all used to work just fine for me, until the upgrade to x11-server
1.1.99, I think.

My external monitor (1280x1024) is now stuck using the resolution of my
 laptop screen (1024x768), which looks terrible. It appears the it cannot
 detect the size of screen so defaults to this.

(WW) RADEON(0): Mode pool is empty
(EE) RADEON(0): No valid modes found
(EE) RADEON(0): No valid mode found for CRTC2, disabling MergedFB
(II) RADEON(0): Total of 0 CRTC2 modes found for MergedFB------------
(--) RADEON(0): Virtual size is 1024x768 (pitch 1024)

Can anyone suggest what has changed to break this?

Thanks,
Nick
